Data is presented comparing the odor-reducing ability of the improved charcoal to conventional activated charcoal, zinc oxide powder, and standard latex foam that has been vulcanized with zinc oxide. Data is also presented showing the comparative odor-reducing ability of latex foam which incorporates various amounts of the improved activated charcoal and standard foam incorporating conventional activated charcoal.
